It has been off of a car and stored in its box since 2017. This has no moving parts, and it worked perfectly fine when it was removed. My car had other aftermarket parts, and it was tuned to work more efficiently with this TMIC. No additional parts or fasteners are included.
It is designed with the shroud to work with the Gen 2 hood scoop. Please see pictures for condition. It is a bit dirty, as it went straight in the box upon removal.
